There is a bug in the implementation of this process step that causes the copy to fail, but it can be fixed for any future workflow and existing workflows.

Resolution resolution

  1. Go to the node /apps/acs-commons/components/workflow/copy-properties/cq:editConfig/cq:formParametersin CRX/DE Lite.

    • Add this String property: PROCESS = "com.adobe.acs.commons.workflow.process.impl.CopyPropertiesProcess".

  2. Find the node of the Copy Properties process step in your existing design-time workflow model in CRX/DE Lite, for example: /conf/global/settings/workflow/models/copy-properties-from-jcr-title-to-dc-title/jcr:content/flow/copy_properties/metaData:

    • Add this String property: PROCESS = "com.adobe.acs.commons.workflow.process.impl.CopyPropertiesProcess".
    • Use the Touch UI to edit the design-time workflow model, save changes, and click Sync to update the run-time model.
